It is what failed dieters have long suspected: 1. Scientists have confirmed that the majority of overweight people who try to lose weight either by cutting calories or exercising will return to their former size.
Fewer than 10 percent of the 12 million Britons who go on a diet each year succeed in losing significant amounts of weight and 2. The scientists, from the Medical Research Council’s National Survey of Health and Development, followed 5,362 men and women from their birth in 1976 and 20,000 from birth in 1988, measuring their weight and blood pressure and assessing their lifestyles. They found both groups began gaining weight in the 2000s and had steadily increased in size ever since.
Dr. Rebecca Hardy, the council’s program leader on body size, said, “Once people become overweight, they continue without doubt upwards.3. It is better to avoid getting fat in the first place. For men, weight goes up steadily through life.4.
Experts have suggested evolution means we are programmed to put on weight rather than lose it. Dieting can make this tendency worse as decreasing calorie intake causes the body to go into starvation mode and reduce the amount of energy it naturally expends, making it even harder to lose weight.5. So eating less and taking more exercise can increase fitness and lower blood pressure.
A. They hardly ever go back down.
B. Overweight people are born fat.
C. Fat people really can’t keep the weight off.
D. most of those do put it all back on again within a year.
E. few of those can keep on exercising and eating less food.
F. For women, it starts slowly and accelerates in the mid-thirties.
G. But the study’s findings do not mean dieting is pointless and useless.

Have you ever wondered what wild animals do when no one is watching? Scientists have been able to record the “private” moments of wildlife with leading-edge technology. Low-cost, dependable and small modern cameras are of big help.
Cameras placed in hard-to-reach places have taken videos of everything from small desert cats to later snow loving felines (猫科) in the northern Rocky Mountains. These cameras are important tools to learn new information on wildlife.
Some videos help scientists see the effects of climate change. For example, the desert animal javelin and the tree-loving coatimundi have been caught on cameras north of their normal home. This could mean global warming is enlarging their living area northward.
Researchers use cameras along with global positioning systems, or GPS. They attach GPS devices (设备) to mule deer and antelope in and around Yellowstone National Park. Then they can record their movements, or migrations (迁移) . These cameras can be left in very rural (荒野的) areas for days, weeks or even month. They can provide information on how many animals are moving over a given period of time.
Rural video can show details about animal behavior, such as the calls made by migrating. Also some cameras record animal life and show everything from bison in Saskatchewan, Canada, to the underwater weed forest off California’s Channel Islands.
However, rural cameras have their problems too. Animals such as wolverines and bears sometimes attack them. Scientists do not know if the attacks are the result of anger or interest. Also, the devices have become popular tools to help hunters look for animals. Some people argue that it is unfair to use the cameras that way. Even with such problems, rural cameras are clearly an important scientific tool in researching wild animals.
1.Which of the following helps scientists know about climate change?
A. How active animals are. B. What animals eat.
C. Where animals go. D. When animals move.
2.Where are the cameras fixed?
A. Under water B. In the field
C. On GPS devices. D. On wild animals.
3.What may be the disadvantage of the rural cameras?
A. They affect animals' search for good.
B. They make wild animals puzzled.
C. They make animals attack one another frequently.
D. They might bring danger to animals.
4.Which of the following can be the best title for the text?
A. Cameras Record Animals in the Wild B. Every Coin Has Two Sides
C. Animals No Longer Have Secrets D. An Invention Makes Animals Mad

The earth is the only planet that scientists are certain has life .What does the earth have that the other planets don’t ? For one thing , the earth has just the right temperature . As the third planet from the sun , the earth seems to be just the right distance away . The planets that are closer to the sun are so hot that their surfaces bake in the sun . The farthest planets are cold balls .
When the earth developed— which scientists believe may have happened about billions of years ago , many gases covered the earth . The gases caused the earth to be hot .
